LTC2657IFE-L12#TRPBF

Overview

The LTC2657IFE-L12#TRPBF is an octal 12-bit digital-to-analog converter (DAC) from Analog Devices, packaged in a 20-lead thermally enhanced TSSOP. It features an integrated 1.25V reference yielding a 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity, and a maximum integral nonlinearity (INL) of ±1 LSB. Communication is handled via a 400kHz I²C interface with selectable power-on reset states.

Feature Summary

Octal architecture with eight independent 12-bit DAC channels
Integrated 1.25V reference providing 2.5V full-scale output range
Ultralow crosstalk between channels (0.8nV·s typical)
Selectable power-on reset to zero-scale or mid-scale

Applications

Mobile communications systems
Process control and industrial automation
Instrumentation and test equipment
Automotive electronic modules

Procurement Notes

Verify the #TRPBF suffix confirms tape and reel packaging for automated assembly. Confirm the 'I' grade designation matches the required -40°C to 85°C operating temperature range for the specific application environment.

Selection Notes

Select this part when eight isolated voltage outputs are required within a compact footprint. The L-option provides a 2.5V span suitable for lower voltage logic interfaces, while the H-option offers 4.096V. Ensure the system supply voltage accommodates the 2.7V minimum requirement for the L-grade variant.

Part Context

This component belongs to the LTC2657 family of I²C DACs. The 'IFE' code specifies the Industrial temperature grade (-40°C to 85°C) and the 20-lead TSSOP package. The 'L12' indicates the 2.5V full-scale internal reference configuration with 12-bit resolution.
